Abstract
The utility model discloses a kind of decanter centrifuge devices of the online ammonia nitrogen removal of sludge, it includes stripping gas cell, stripping gas cell includes: housing, it is located at going out outside liquid phase for decanter centrifuge, the bottom of housing has leakage fluid dram, and the top of housing has an opening, opening is connected through first pipe with the entrance of the first blower, and the outlet of the first blower is connected through second pipe with gas concentration unit；Second blower, one end are connected with atmosphere, and the other end is connected with total discharge pipe, are connected on total discharge pipe and multiple separate air hose.Air is accelerated into high-speed flow by the second blower by the utility model, the liquid phase formation that goes out of air-flow and decanter centrifuge liquidates, by the ammonia nitrogen abjection in liquid phase, simultaneously, liquid and liquid ruptures effect after housing high-speed impact when going out liquid using decanter centrifuge, so that liquid is formed a large amount of droplets, increases the contact area of liquid and air-flow, to further improve the eliminating efficiency of ammonia nitrogen.
Description
Technical field
The utility model relates to the centrifugations of the sleeping spiral shell of decanter centrifuge technical field more particularly to a kind of online ammonia nitrogen removal of sludge
Machine device.
Background technique
After high temperature pyrolysis municipal sludge, organic matter broken wall in sludge releases a large amount of ammonia nitrogen in a liquid.Because of gas
The solubility of body in water reduces as the temperature rises, so making full use of in the state of being pyrolyzed mud still in high temperature
The condition of high temperature realizes the abjection of part ammonia nitrogen, can largely save the cost of back segment treatment process removal of ammonia and nitrogen.
Utility model content
The technical issues of in the presence of the utility model mainly solution prior art, to provide a kind of removal of ammonia and nitrogen effect
The decanter centrifuge device of the online ammonia nitrogen removal of the good sludge of fruit.
Above technical problems of the utility model are mainly solved by the following technical scheme:
The decanter centrifuge device of the online ammonia nitrogen removal of sludge provided by the utility model comprising stripping gas cell, institute
Stating stripping gas cell includes:
Housing, is located at going out outside liquid phase for decanter centrifuge, and the bottom of the housing has leakage fluid dram, and the housing
Top there is an opening, the opening is connected through first pipe with the entrance of the first blower, the outlet of first blower
It is connected through second pipe with gas concentration unit；
Second blower, one end are connected with atmosphere, and the other end is connected with total discharge pipe, connect on total discharge pipe
Have it is multiple separate air hose, it is each described separate air hose and tilt upward extend into the housing, and with the decanter centrifuge
Go out liquid phase position it is corresponding.
Further, the entrance of second blower is connected through air filter with atmosphere.
Further, ammonia nitrogen online monitoring instruments are connected on the second pipe.
Further, the air hose and the angle of horizontal plane of separating is 45-60 degree.
The utility model has the beneficial effects that: air is accelerated into high-speed flow, air-flow and sleeping spiral shell by the second blower
The liquid phase formation that goes out of centrifuge liquidates, and the ammonia nitrogen in liquid phase is deviate from, meanwhile, liquid and housing when going out liquid using decanter centrifuge
Liquid ruptures effect after high-speed impact makes liquid form a large amount of droplets, increases the contact area of liquid and air-flow, thus into one
Step improves the eliminating efficiency of ammonia nitrogen.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the decanter centrifuge device of the online ammonia nitrogen removal of sludge of the utility model.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
As shown in fig.1, the decanter centrifuge device of the online ammonia nitrogen removal of the sludge of the utility model comprising stripping gas
Unit, stripping gas cell include:
Housing 1, is provide with 1 going out outside liquid phase in decanter centrifuge 13, and the bottom of housing 1 has leakage fluid dram 2, and housing 1
Top there is an opening 3, opening 3 is connected through first pipe 4 with the entrance of the first blower 5, the outlet of the first blower 5 the
Two pipelines 6 are connected with gas concentration unit 7；In the utility model, liquid phase can be increased on the basis of former decanter centrifuge and gone out
The cavity volume (increase former volume 30%) of mouth position, uses as housing 1.
Second blower 8, one end is connected with atmosphere, and the other end is connected with total discharge pipe 9, connects on total discharge pipe 9
Have it is multiple separate air hose 10, each separate air hose 10 and tilt upward and extend into housing 1, and go out liquid with decanter centrifuge 13
Phase position is corresponding.In the utility model, the direction and liquid flow direction for separating air hose 10 are in liquidating state, so as to by liquid phase
In ammonia nitrogen abjection.
Air is accelerated into high-speed flow, the liquid out of air-flow and decanter centrifuge 13 by the second blower 8 by the utility model
It is mutually formed and is liquidated, the ammonia nitrogen in liquid phase is deviate from, meanwhile, liquid and 1 high-speed impact of housing when going out liquid using decanter centrifuge 13
Liquid ruptures effect afterwards makes liquid form a large amount of droplets, increases the contact area of liquid and air-flow, to further improve
The eliminating efficiency of ammonia nitrogen.
Preferably, in order to improve the air-flow degree of purity for separating the outlet of air hose 10, the entrance of the second blower 8 is filled through air filtration
11 are set to be connected with atmosphere.
Preferably, ammonia nitrogen online monitoring instruments 12 are connected on second pipe 6.Preferably, air hose 10 and horizontal plane are separated
Angle be 45-60 degree.In the utility model, after decanter centrifuge 13 starts normally to feed, all blowers and instrument are opened,
By the numeric feedback of ammonia nitrogen online monitoring instruments 12, the revolving speed of the second blower 8 is adjusted, to reach optimal ammonia nitrogen removal effect
Fruit.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
